Transapical beating heart septal myectomy learning curve and training of future surgeons: an observational study.
Int J Surg
December 2024
Division of Cardiovascular Surgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, People's Republic of China.
Background: Description of the learning curve for transapical beating heart septal myectomy (TA-BSM) helps to understand the potential for wider adaptability. The authors elaborate and examine a competency-based training assessment for TA-BSM that could serve to disseminate septal myectomy expertise.
Materials And Methods: Data on 177 consecutive patients who underwent the TA-BSM for hypertrophic obstructive cardiomyopathy (HOCM) between April 2022 and June 2023 was collected prospectively, which was registered on ClinicalTrials.
Left Bundle Branch Area Pacing Compared to Right Ventricular Outflow Tract Septal Pacing: Mid-term Results and Learning Curve.
J Innov Card Rhythm Manag
December 2024
Arrhythmia Unit, Department of Cardiology, University Hospital Clinico Lozano Blesa, Zaragoza, Spain.
Our study evaluated the efficacy and feasibility of left bundle branch area pacing (LBBAP) compared to right ventricular outflow tract septal pacing (RVOSP). We conducted a prospective, single-center, observational study involving 200 consecutive patients who required pacemaker implantation. The patients were divided into two groups (LBBAP and RVOSP), with 100 patients in each group.

Disorders of the pulmonic valve (PV) receive considerably less attention than other forms of valvular heart disease. Due to the dramatically improved survival of children with congenital heart disease over the last 5 decades, there has been a steady increase in the prevalence of adults with congenital heart disease, which necessitates that clinicians become familiar with the anatomy and the evaluation of right ventricular outflow tract and PV anomalies. A multimodality imaging approach using echocardiography, cardiac computed tomography, and magnetic resonance imaging is essential for a comprehensive evaluation of the anatomy and function of the right ventricular outflow tract, PV, and supravalvular region.

Background: Safe and effective pediatric blood pumps continue to lag far behind those developed for adults. To address this growing unmet clinical need, we are developing a hybrid, continuous-flow, magnetically levitated, pediatric total artificial heart (TAH). Our hybrid TAH design, the Dragon Heart (DH), integrates both an axial flow and centrifugal flow blood pump within a single, compact housing.

Department of Cardiothoracic and Vascular Surgery, Deutsches Herzzentrum der Charité, 13353 Berlin, Germany.
The HeartMate 3 (HM3, Abbott) left ventricular assist device (LVAD) is the only commercially available option considered suitable for long-term circulatory support. External compression of the outflow graft causing obstruction (eOGO) is a serious adverse event affecting patients on long-term support. The obstruction occurs due to the accumulation of gelatinous substance between the bend relief and outflow graft.
